Question

Describe the process of subduction and how volcanoes form. How does the movement of tectonic plates cause volcanic activity?

Answer 1

Explanation:

A subduction zone forms when continental crust and oceanic crust collide. The continental crust is thicker and more buoyant than the oceanic crust so the oceanic crust subducts beneath the continental crust. ... Volcanoes associated with subduction zones generally have steep sides and erupt explosively.

Volcanoes form when tectonic plates collide and one plate is pushed beneath another. Tectonic plates also move away from one another to produce volcanoes. Hot magma rises from the mantle at mid-ocean ridges pushing the plates apart. ... This molten rock then rises and erupts on the surface building up a volcano.
